1. OPERATION

1.1 INTRODUCTION

Your RAY53 has the capability to transmit and receive on all available US,International and
Canada Marine VHF radiotelephone channels. There are channels that are FCC approved
but may only be used by authorized st atio ns for specif ic p urpos es, depend in g on the ty pe of
vessel (commercial or noncommercial.) Refer to Table 1-1 . These table list all of the marine
VHF channels available in your RAY53 for Canada,International and U.S. radiotelephone
use. Full familiarization with this table is essential when selecting your channels. The
International frequencies were agreed upon by the attending countries at the 1968
International Telecommunication Union meetin g in Genev a and ar e in activ e use around the
world. The US channels are t hose channels authorized for use in the U.S.A. by the FCC.

1.3 OPERATING PROCEDURES

1.3.1 Turning the Power O n

1) Rotate the VOLUME knob clockwise to turn t he radio on.

1.3.2 Setting the Volume

1) Rotate the VOLUME knob for the disired volume level.

1.3.3. Setting the Power Output

1) Simply press the “MON 1/25” key for two seconds to toggle bet w een 1 Watt output
and 25 Watt output. When “1 WATT” is d isp layed,the output power is 1 Watt.
If “1 WATT” is extinguished, 25w at t s is being output. The choice of p ower output is
dependent upon the distan ce of transmission and tran smitting conditions. I n cert ain
US harbors and on certain channe ls, the FCC requires the power to be limi t ed to
1 Watt. On these “required “ channels,the radio automatically selects 1 Watt power
output when the channel is selected.

1.3.4 Selecting the Channel

1) To select the appropriate channel, rotate CHANNEL SELECTION Knob clockwise /
counterclockwise or also press U P/ DOWN key of the microphone.

2) The channels which are not set on the frequency mod e are skipped .

3) When UP/DOWN key is continuously pressed for over 0.5 seconds,the channel is
continuously changed(+1 or – 1) every 100msec during pressing UP/DOWN key.

1.3.5 To select the frequency mode

1) The frequency mode(group) can be selected from US mode, International mo de and
Canadian Mode.
The frequency mode can be shown on the LC D as follows.
USA frequency mode---------------------------­ CANADIAN frequency mode------------------

Æ

“INT” and “CAN” are eliminated

Æ

“CAN” is displayed and “INT” is
eliminated.
INTERNATIONAL frequency mode----------

Æ

“INT” is displayed and “CAN” is

eliminated.

When WX/INT key is pressed and held for ov er 2 seconds, one frequency mode
can be changed to the other frequency mo de and Alerm 1 is heard.:
For example:
When USA mode is in use,it can be changed to CANADIAN mode by doing above
operation.
When Canadian mode, it can bew ch anged to International mode. When
International mode,it can be changed to USA mode. The last changed frequency
mode can be memorized.
When the power is turned on,the last memorized frequency mode can be
used.(Channel number is16C H at t hat time.)

1.3.6 To Transmit

1) Press the Push-To-Talk switch(PTT switc h) and speak into the microphone using a
clear normal voice.

2) If the current channel is Weather CH or the Tx prohibit ed channel, PTT switch c annot

be used and Audible beep sound 2 is heard.

3) RAY53 is designed to meet the new FCC Rules Part 80.203, which states,i f the PTT
switch is pressed continuously for over five minutes, t r ansmission is forcibly in hibited.
If this occurs,audible b eep sound 2 will be heard until the PTT switch is released.

1.3.7 To select a Weather Chan nel

1) Simply press the WX/INT,then use Channel Selection Knob or UP/DOWN key to
select the desired Weather Channel from 0 to 9. When this mode is selected,the

transmitter is always inhibited.

2) When the Weather CH is finished by pressing WX/INT key,the last used Weather CH

number is memorized

3) When the power is re-turned on,t he memorized Weather CH number can be

activate on the Weath er CH mode.

1.3.8 Priority Channel

1)When 16/9 is pressed and released, Alarm 1 is heard and Pri orit y Channel is in use then
Channel Display(Sma ll) shows “P” on the LCD.(“P” display means “Priority CH”.)

2) When 16/9 key is pressed and rele ased again during “P” is diplayed, A lerm 1 is heard
and the channel will be returned to the privious Working CH. When the channel is
changed by UP/DOWN key during Priority CH is displayed, “P” display will be
eliminated and Workimg C H wil l be in use.

3) When 16/9 is continueously pressed for over 2 seconds, Alerm 1 is heard and Priority
channel can be changed either 16CH or 9CH.( When Priority CH is 16CH, it can b e
changed to 9CH and when Pr iority CH is 9CH,it can be changed to 16CH.)

1.3.8 Channel Memory

1) The RAY53 has the capability of memorizing all US,Internationa l and Canadian
Channels. The channels memorized will be scanned in the Me mory Scan mode.

2) Channel Memory: When SCAN/MEM key is pressed a nd held for over 3 seconds,the
audible beep sound 1 is heard and the selected current channel can
be put into memory.
When the displayed channel on the LCD is memor iz ed, “MEM” is
displayed on the LCD.
Memory Clear : To press and hold for 3 seconds w hen the memory channel is
stored, the audible beep sound 1 is heard and the channel c an be
cleared

When the displayed channel is not memorized,”MEM” is not
displayed on the LCD.

1.3.9 Scan Modes

The RAY53 is equipped with two types of scan options, All-scan and Memory Scan. How these
options are accessed is dependent upon whether there are any channels stored in memory.

1) All-Scan mode
If no channels are stored in me mory,when the SCAN/MEM key is pressed and
released, the audible beep sound 1 is heard and ”SCAN” will begin to flash on the LCD for
three seconds. If no other keys are pressed in these three seconds,the radio will begin
scanning all channels(exce pt weather chann els) as long as no signal is receiv ed. If a signal is
received,the scan will stop on the receiving channel. If the signal is lost for five seconds, the

radio will resume scanning. While the radio is s cannin g ALL-Scan, ”SCAN” is disp layed on the
LCD.
To cancel the scan mode,press the SCAN/M EM key while the radio is scanning.

2) Memory Scan mode
If one or more channels are stored in me mory,when the SCAN/MEM key is pressed and
released, the audible beep sound 1 is heard and “SCAN” and “MEM” will begin to flash
simultaneously on the LCD for 3 seconds. If no other key is pressed in these three seconds,
the radio will begin scanning all channels currently in memory.(Begin Memory scanning) As
with All-Scan, If a signal is received,t he scan will stop on the receiving ch annel until the s ignal
is lost for five seconds, the radio w i ll resume scanning.
While the radio is scanning M emory Scan, “SCAN” and “MEM” are displayed on the LCD.
To cancel memory scan,press the SCAN/MEM key w hil e t he radio is scanning.

When SCAN/MEM key is pressed again during “MEM” flashing within these three
seconds, the audible beep soun d 1 is heard and “SCAN” will flash on t he LCD and the
radio will begin ALL Scan mode. “MEM” will disaprear from the LCD leaving only “SCAN”
flashing.

1.3.10 Monitor operations

1) The RAY53 is equiped with 2 types of monitor operations, Dua l Watch opeartion and
Tri Watch operation.
Working CH and Priorit y CH can be monitored altern at ely in Dual Watch operat ion.
Working CH, Priority CH and Weather CH can be monitore d by turns in Tri Watch
operation.

2)Dual Watch and Tri Watch can be changed each other by usin g WX/INT key.
When WX/INT key is pressed and released in the monitor mode, Alerm 1 is heard
and Dual Watch and Tri Watc h can be changed each other alter nat ely.
